Predicting shear strength in reinforced concrete deep beams through finite element modeling of diverse concrete materials

Erkan Polat, Gökhan Karaman

Challenge Journal of Structural Mechanics (2025) 11(1) 24-41

This study investigates the prediction of the strength of reinforced concrete deep beams, critical components in urban infrastructure, by evaluating their load-carrying capacities through finite element modeling and nonlinear inelastic analyses using LS-DYNA s...
Enhancing the mechanical performance of perforated steel plates through fiber-reinforced composite reinforcement: A finite element analysis study

Husam A. M. Alshabrawi, Habib Uysal

Challenge Journal of Structural Mechanics (2025) 11(4) 174-183

Reinforced concrete and steel plates are widely used in civil engineering and are important components of many structural systems and ground reinforcement projects. These plates effectively carry different loads, enhance ground support, and improve the durabil...
Effect of different trimline extension of clear aligners in combination with Class II elastics on the mandibular dentition: a finite element analysis

Nurver Karslı, Bahanur Hilal Kisbet

Challenge Journal of Structural Mechanics (2024) 10(2) 58-68

Objective of this study is to evaluate the effect of different trimline extension of aligners and the effect of elastics applied through the slit cutouts and buttons on the mandibular dentition using Class II intermaxillary elastics combined with clear aligner...
Nonlinear in-plane response of 3D-printed concrete walls with varied infill patterns: Experimental mix design and numerical structural assessment

İsmail Hakkı Tarhan, Yeşim Tarhan

Challenge Journal of Structural Mechanics (2025) 11(3) 160-173

This study investigates the nonlinear in-plane structural behavior of 3D-printed concrete wall elements with two representative internal infill patterns ‒ lattice (L) and triangular (T) ‒ using finite element modeling informed by experimentally derived materia...
Mechanical and durability study of nano-SiO2 and nano-TiO2 on fiber reinforced concrete

Awadhesh Srivastava, Abhishek Mishra, Sachin Kumar Singh

Challenge Journal of Concrete Research Letters (2025) 16(1) 33-39

This work presents the results of an experimental investigation into the strength and durability properties of fiber-reinforced concretes that have polypropylene (PP) fibers added to the concrete by volume and nano-SiO2 (silicon dioxide) and nano-TiO2 (titaniu...
